Serial No. 541,584.

To all whom 'it may concern:

Be it known that I, ELZY R. WiLLrAMs, a citizen of the United States, and a resident of St. Joseph, in the county of Buchanan and State of Missouri, have invented a new and Improved rI`rigger Mechanism, of which the following is a full, clear, and exact description.

The invention relates to trigger mechanisms such as shown and described in the Letters Patent of the United States, No. 938,192, granted to me on October 26, 1909.

The object of the present invention is to provide certain' new and useful improvements in trigger mechanisms, whereby an auxiliary trigger can be readily set for aetion whenever it is desired to provide a sensitive action of the trigger mechanism.

For the purpose mentioned, use is made of an abutment mounted to swing on the pivot of the main trigger, to abut against a fixed part of the firearm, a spring-pressed manually-controlled mechanism mounted on the main trigger and adapted to engage the said abutment, and an auxiliary' trigger fulcrumed on the main trigger and provided with a catch, adapted toengage the said mechanism, vto hold the latter under tension and against the said abutment, so that when the auxiliary trigger is pressed the main trigger is released.

A practical embodiment of the invention is represented in the accompanying drawings orming a part of this specification, in which similar characters of reference indicate corresponding parts in all the yiews.

Figure 1 is a side elevation of the trigger mechanism as applied to a breech-loading firelarm, thestock of which is shown in section; Figure 2 is an enlarged elevation of the left-hand side of the trigger mechanism and showing the auxiliary trigger out of action; Fig. 3 is an elevation of the righthand side of the trigger mechanism, parts bein in section; Fig. Llis an elevation of the orward edge of thetrigger mechanism; Fig. 5 is a like view of the rear edge of the triggermechanism; Fig. 6 is an elevation of t e left-hand side of the trigger mechanism with the auxiliary trigger set for action and the main trigger 1n engagementl with the hammer; and Fig` 7 is a similar view of the right-hand side of the same.

The nre-arm on which the trigger mechanism is applied, consists of the usual stock A, the barrel B, the hammer C, the spring C, the main trigger D, mounted to swing on a pivot D and pressed on by a main trigger spring D2, the breech block E and the lever F tor operating the breech block E and for forming the trigger guard.

An auxiliary trigger G is arranged on the front of the finger piece of the main trigger D, and is pivoted at G in a central yslot of the said finger' piece and pressed on by a spring G2, the swinging movement of the auxiliary trigger G being limited by a stop pin G3, as plainly indicated in Fig. 3. A catch G4 extends angularly from the pivotal end of the auxiliary trigger G, and is adapted to engage the upper end of a lever H, fulcrumed at its lower end at H in the slot of the main trigger D, and the said lever H is provided with a spring H2 bearing against a pin H3, held on the main trigger D, so as to normally hold the lever H in a rearmost position, as indicated in Fig. 8. On the lever H is secured a handle H", projecting through a slot D?s on the right hand side of the main trigger D, so tha-t the operator can take hold of the handle Ht,

with a view to swing the lever H forward` against the tension of its spring H2 and Jfor engagement with the catch G4 of the auxiliary trigger G (see Fig. 7). -On-the lever H, at a point between the pivot H and the handle H1 is secured a pin H5, working in the slot D' in the main trigger and engaging the forked end I of a setting lever I, fulorumed at I2 on the side of the main trigger D. The lower end of the lever I is adapted to engage an angular arm J formed on the free end of a heavy spring J, secured at its upper end J2 to the side lof the main trigger D, as plainly indicated in Figs. 2 and- 6. The upper pointed end I3 of the lever I is adapted to engage a block K, held on an arm K, fulcrumed at K2 on an abutment L, hung loosely on the ivot D of the main trigger D and extending down on the side of the main trigger on which the setting lever I is pivoted. A spring K3 presses the block K, to hold the same normally in a downward position again-st a stop pin K4, carried by the abutment L, so that when the lever'H 1s swung forward by the operator, as previously mentioned, then the pin 'Hi imparts a swinging motion to the lever I, so that the pointed end I3 engages and raises the block K, to finally pass the same, after which the block K is pressed back to its previous position by its spring K", to be finally engaged by the pointed end I'of the lever I, as plainly shown in Fig. 6, to hold the setting lever I in a locked position. The abutment L is pressed on by a spring L,fto normally hold the same in a forward position, and on the forward end of the abutment L is secured an adjustable screw pin L2, adapted to abut against a shoulder A formed on the frame,l and which shoulder is preferably the forward wall of the slot through which extends the main trigger D. y

The operation is' as follows: TWhen the several parts are in the position shown-in Figs. l, 2 and 3, then the auxiliary trigger` G is out of action and the main trigger D is used in the usual manner, for releasing the hammer C. When it is .desired to make use of the auxiliary trigger G, then the operator takes hold of the handle H4 and pushes the same forward, so as to engage the lever H with the catch G4 of the auxiliary trigger G, and to impart a swinging motion to the setting lever I, so as to engage the block K thereof and to place the spring J under tension. Now as the spring J bears'on the lower end of the lever I, the

' upper pointed end I3 thereof presses against the block K, so as to hold the pin L2 in firm abutment with the shoulder A of the frame. The hammer C is now cocked in the usual manner, and when the operator slightly presses the auxiliary trigger Gr in a rearward direction, then its catch G4 disengages the lever I-I, thus releasing the same and allowing its spring H2 to swing the lever H rearward, andalso allowing the spring J to press on the lever I, to force the main trigger D in a rearward direction, as the upper end I3 of the lever I is held against swinging movement by abutting against the block K mounted on the abutment L, abutting with its pin L2 on the shoulder A. Thus when the main trigger D is swung rearward as described, it releases the hammer C and the fire-arm is discharged. y

It is understood that when the lever H is released by the auxiliary trigger Gr," it swings backto its normal rearward position, as before mentioned, so that after tliefire-arin is discharged the several parts are again in normal position with the auxiliary trigger out of action, vand whenever it is desired to re-use the auxiliary trigger, it has to be raised by lthe operator manipulating the handle H4, as previously explained.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

l. A trigger `mechanism for rearms,

comprising a main trigger, an abutment mounted to swing and adapted to abut against a xed part of the fire-arm, a springpressed manually controlled mechanism mounted on the said main trigger and adapted to engage the said abutment, and an auxiliary trigger fulcrumed on the said main trigger and provided with a catch adapted to engage the said mechanism to hold the latter under tension and against the said abutment.

2. A trigger mechanism for fire-arms, comprising a main trigger, an abutment hung loosely on the pivot of the said main trigger' and adapted to abut against a fixed part of the 1irearm,a spring fixed on the said main trigger, a manually-controlled device mounted on the said main trigger and adapted to place the said spring' under tension and to abut on the said abutment, and an auxiliary trigger adapted to engage and lock the said mechanism in active position.
